Thermo Scientific Slide-A-Lyzer Buoy Cassette Float 16 Buoys

Thermo Scientific 66432 Slide-A-Lyzer™ Cassette Buoy (Gray, 70 ml Capacity)

The Thermo Scientific 66432 is a high-buoyancy flotation accessory specifically designed for the 70 ml original-format Slide-A-Lyzer™ Dialysis Cassettes. Engineered to support the significant weight of a fully loaded 70 ml vessel, this gray buoy ensures the cassette remains suspended in a vertical orientation within the dialysis buffer. Maintaining this upright position is vital for maximizing the surface-area-to-volume ratio, facilitating rapid diffusion and efficient salt removal. Manufactured from durable, high-density, closed-cell foam, the 66432 is chemically resistant and designed for repeated use in demanding laboratory environments.

Technical Performance and Design

• High-Volume Support: Specifically calibrated to provide the increased displacement necessary to float the 70 ml cassette format, even when filled to maximum capacity.

• Vertical Alignment: Keeps the dialysis membranes positioned vertically, ensuring that the entire surface area of both membranes is exposed to the buffer for optimal exchange kinetics.

• Closed-Cell Foam Technology: The gray synthetic foam is non-absorbent and resistant to moisture and common laboratory buffers, ensuring it retains its buoyancy and structural integrity over time.

• Secure Friction Fit: The center slot is precision-cut to provide a tight grip on the 70 ml cassette frame, preventing accidental detachment during stirring or buffer changes.

Key Benefits & Applications

• Optimized Large-Volume Dialysis: Essential for large-scale protein purification and desalting where 70 ml volumes are processed in large beakers or carboys.

• Membrane Protection: Suspends the sample safely away from the bottom of the container, preventing the delicate regenerated cellulose membranes from contacting magnetic stir bars.

• Visual Monitoring: The gray color allows for easy color-coding and identification of samples when multiple dialysis projects (using different MWCOs or sample types) are running in the same laboratory area.

• Easy Maintenance: Chemically inert surface allows for quick decontamination with 70% ethanol or rinsing with deionized water between uses.
